Question(s) from the Census form

Has the person been told by a doctor or nurse that they have any of these long-term health conditions?

How this variable is created

This variable is derived from responses to the long-term health conditions question and aims to capture people who have specific combinations of health conditions (known as comorbidity).

Where a respondent selects ‘Diabetes (excluding gestational diabetes)’ and ‘Kidney disease’ they are coded to 1 ‘Has diabetes and kidney disease’. The respondent could also have other long-term health conditions, but those conditions are not recorded in this variable. All other combinations of responses, including ‘No long-term health condition’ are coded to 2 ‘Does not have diabetes and kidney disease’.

If a person has more than one specified combination of long-term health conditions, they will be captured in more than one comorbidity health variable.

History and changes

This is a new variable for 2021.

Data use considerations

If a person has more than one specified combination, they will be captured in more than one comorbidity health variable.

This variable does not have a non-response rate as it is created during Census processing by using responses from one or more questions on the Census form. For the item non-response rate for the health question, see CLTHP.
